BY a g ATTORNEYS WITNESSES fill vvsrdly from the rear ends oi certain of the air nessoges 12, then iorwurdly through certain of the air passages 12, and then u weirdly end reurvvurdly through certain o the air pesssges 12. The boxes 13 and let will be de 55 signed to harmonize With the size and design or the radiator. in order to cause the sir to circulate in the manner set forth, the front box 13 will be smaller than the rear box it, being ep g roximutely one-lnili the size m of the loo: is. lunch of the boxes has a merginel flsngelli. Bolts 16 extend through the radiator and the flenges 15 to securely hold the boxes in place. it will be apparent that the hon it extends or "falls helovv the lower 65 well of the front hon 13.. This will cause on:

This invention relates to e hester for entoinohiles which utilizes the heat of the Writer of the engine cooling system thereoi, for the purpose of heating the drivers end passen- 5 ger compartments of the automobile.

'lhe invention has for its general object the provision of improvements in s heater oi the indicated character, whereby the heat may he controlled and regulated to compensate for 9 Weather temperature chsn es; whereby at large volume of hot sir rosy e obtained from the radietor of the automobile; and whereby the heater will be oi simple and substantial p design well suited tor economic manufac- The nature oi: the invention and its distinguishing features and udvuntoges will uppeer when the following snecificution is reed in connection with thenccompn-nying drewpossing into certain of the eir passages 12 to enter the resr box is, The rear icon it has n horuzontsl partition 1.? which causes the sir entering the lower port of the hon i l 79 to circulote forwardly through certain of the pssseges 12 into the hon 13. ilhe provision of the partition 1? provides u hot air cheniher 18 at the top of the hot. it. The air entering the front hos. i3 is caused to circulate 75 reurvverdiy through certain of the air pessnges 12 into the chomher 18. The chamber 18 hos e not eir outlet 19.

The hot air is fed from the outle 19 by e conduit or pipe heving one end connected $0 with the outlet 19 in any suitable nsenner and its opposite end being connected with n fitting 21 having it register, 22 with vsriohle openings at one end on the dash 23 to discharge hot air into the front compartment of the automobile. A conduit or pipe or has one end thereofconnected in any suiteble monnerwith the fitting 21 in communication with the interior thereof, and its opposite 90 end is connected in any suitable manner with a register 25 hevingverieble openings to discharge hot air into the resr compartment of the outoinohile. The registers 22 and 25 may he of sny preferred conventional type. lit or; will now he understood that hot air Will he forced reervvsrdly by the pressure of the air entering the rodietor 10 in the forward movement of the automobile. This hot air will he forced through the pipe 20, fitting 189 ing, in which Figure l is s side view, partly in section showing at heater einhodying the features 0 the invention in conjunction with certein oppurtenences of on automobile; V Figure 2 'is it rest elevation oi the u per 1 port of the outoinohile radiator and s owing the rear eir circulcting herds applied thereto L Figure 3 is a, front elevation of the upper 39 port or? the rodietor and showing the front air circulating beliie applied thereto;

Figure t is e verticsl section of the upper port of the radiator and the front end resr w sir circuleting hefies as applied thereto; Figure 5 is a section showing the hot sir cutout valve 3 Figure 6 IS a, view of one of the details. Referring now more particularly to the a drervin it will he apparent that the emhodirnent o'- the invention illustrated includes a radiator 10 forming at part of the engine cooling system oi an automobile. The redintor it includes the usual hot water compartment having a lower Wall 11. The radiator 10 also includes air passages 12 which extend through the some from the front to the reer thereof. Buides, in the form of ooxes consisting of at front h0g1? and a rear box 14 are secured to the radiator 10 to close the trout and reer sections thereof to cause sir to circulate upwall to allow air to flow t 21 and pipe 24 into the front and rear compartments of the automobile.

In order to obtain a forced circulation of air while the automobile is at a standstill, and while the water in the radiator is still heated, there is provided a small fan 26 in an enlarged section of the fitting 21. The fan 26 may be operated in anypreferred manner, and in the present instance is operated by an electric motor 27 In order to control the circulation of hot air from the outlet 19 there is provided a cut-out valve member 28 which is pivoted as at 29 and which controls an opening 30 in the fitting 21. The member 28 may be moved to an opened and closed position by any suitable means 31 under the control of the driver of the automobile. The valve member 28 opens inwardly, as shown in Figure 5, and W111 cause the hot air entering the fitting 21 from the pipe 20 to discharge through the opening 30 into the hood of the automobile. The provision of the cut-out valve member 28 makes it possible to shut ed the hot air to the registers 22 and 25. It will also be understood that each of the registers 22 and 25 may be closed while the valve member 28 is in its closed position in the opening 30.

In accordance with another feature of the invention, the rear box 14 has a removable rear wall 32 which is detachably held in place by suitable fastening elements 33 which are received respectively in keyhole slots 34: in the four corners of the wall 32. By loosening the fastening elements 33, the wall 32 may be lifted up slightly and then be separated from the elements 33. The air may then pass through the box M instead of circulating upwardly. This will increase the cooling efficiency of the radiator 10 during the summer months when it is not necessary to heat the interior of the automobile driver and passenger compartments.

It is to be understood that the boxes 13 and 14 may be of any referred proportions with respect to each 0t er, and also with respect to the radiator to which they are ap lied. These boxes may be of any size and esi n in order to harmonize with the size and design of the radiator. If desired, a suitable gasket 35 may be arranged between each box and the radiator as shown in order to make an air-tight fit.

What is claimed is:

1. In a heater of the class described, the

combination of a radiator having air pas sages extending therethrough, and boxes closing front and rear sections of said radiator to cause air to circulate upwardly and forwardly and then u wardlyand rearwardly, and said rear box. avin a removable rear lirough the radiator in the usual way when said wall is removed.

2. In a heater of the class described, the

combination of a radiator havin air passages extending therethrough, and box baffles applied to ront and rear sections of said radiator, the baflle at the rear being larger than the baflle at the front and extending below the lower end of the latter, whereby air is caused to travel in a tortuous path through said radiator, the rear baflle having a part which may be removed to allow air to pass directly through the air passages in the usual manner.

3. In a heater of the class described, in combination, a radiator having air passages extending therethrough, an air baflle secured in relation to a rear section of the radiator to gather air-to be heated by the radiator, and means secured to a baflle which cooperates with saidbafile to convey the heated air away from the radiator, and said baflle having a removable part to allow the flow of air through the radiator in the usual way when said part is removed.
